claim.

In the accompanylng drawings, Figur 1 is a side elevation of a shoe having my improved device affixedthereto, and Fig. 2 is a bottom view of the shoe with the device as in Fig. 1. Fig. 3 is an enlarged bottom view of the device alone, and Fig. is a cross section on line 4%, Fig. 3. Fig. 5 is a cross section on line 55, Fig. 3.

The'device as thus shown comprises two sections or parts a, and b slidably related and confined together in this instance by overturned edge portions 2v and 8 on one of said parts across the edgesof the other part; or equivalent means, and provided. each with a jaw 4 and 5 respectively at its outer end adapted to clamp over or upon the, sole of a shoe in the instep relatively as seen in Figs. 1' and 2, and to fasten the device firmly on the shoe. The larger or main part a; has a forward extension or tongue 6 on the bottom and front of which are two sharp teeth or spurs 7, and which come forward a sufficient distance beneath the instep and have sufficient depth in themselves to more or less penetrate the ice or icy surface or street for which they are intended, but are not so far forward nor of such length that the device itself comes into the flat tread of the shoe or interferes with the walking on ordinary pavements. In other words the said spurs are the forward inclined shank portion of the instep and in a precautionary but not obstructive position and where the shoe is Copies of this patent may Specification of Letters Patent.

merely supplemented by spurs which will penetrate sufficiently to make walking safe on slippery surfaces. The said jaws or lips 4t and'5 are curved somewhat both lengthwise and in cross section to conform to the they are afiixed, and the extremity of lever 8 is bent inward at its extremity to avoid interference in walking. a

A light metal is employed to make all the parts and the sections a and Z) are drawn together and clamped on a shoe by such means as a lever 8 pivoted to rotate hori- Zontally on the bottom of part a and having a link connected therewith near its pivot 10 and with the said part 5 near its middle. The said parts are so constructed and re lated that when the device is clamped in place on the shoe the link 9 will be drawn across the dead center of pivot 10and thus lock the device in place. A reverse movement ofthe lever releases the device.

Vhat I claim is:

An ice creeping attachment for the instep of a; shoe comprising a main plate having one edge curled downward and inward to engage on the edge of the sole and provided with opposite parallel upwardly and inwardly turned edges transversely of the shoe forming guide-ways and having a forwardly projected portion widened at its eX- tremity andpointed spurs on said extremity.

adapted to come under the forward portion of the instep, an auxiliary plate slidably mounted in said guide-ways and having a curled outer edge adapted to engage the edge of the sole, and a lever pivoted on said main plate and a link engaging the lever with said auxiliary plate to clamp said plates on the shoe.

In testimony whereof I aiiix my signature in presence of two witnesses.
